You give your baby amoxicillin for an ear infection. A day later, red spots appear. Panic sets in. Is it serious? As a parent and health writer who’s faced the same scare with my child, I understand how worrying this can be.
Don’t worry—many babies get a rash after taking antibiotics. It can be scary, but not all rashes mean danger.
There are those kinds of rashes which are mild and disappear. Other ones can be indicators of an allergy. Being aware of the distinction can make you stay calm and act accordingly.

Let’s look at what an amoxicillin rash is and when to call your doctor.
What Does an Amoxicillin Rash Look Like?
The appearance of an amoxicillin rash depends on the reason why the rash occurred.
Non-allergic rash comes out as flat, pink patches. They can appear on the chest, back or stomach. They do not itch. This rash can appear 3–7 days into taking the meds.
An allergic rash is not the same. It sort of looks like red, bumpy-looking, they are like hives. These bumps are itchy and contagious. This type can develop in as little as a few hours.
Observe when the rash will start and how it will appear. That will tell you if it is a reaction or not.
